Which practice directly reduces drift of pesticides to non-target vegetation?

• A. Apply according to label
• B. Set appropriate pressure and nozzle
• C. Use drift reduction techniques
• D. Maintain buffers

Answer: (C)

Drift reduction is the direct way to keep pesticide from moving off target. Drift reduction techniques focus specifically on how the spray behaves in the air—things like using drift-reducing nozzles, choosing droplet sizes that minimize off-target movement, lowering boom height, adjusting spray pressure, and applying in conditions that limit wind. All of these actions target the mechanism that causes droplets to travel away from the intended area, helping the spray stay where it’s supposed to.

Applying according to the label is essential for safe and effective use, but it isn’t a drift-specific method. Setting pressure and choosing a nozzle influence drift risk by shaping droplets, and while important, they are part of drift control rather than the broad category of drift reduction techniques. Maintaining buffers helps shield non-target vegetation by distance, which reduces potential contact, but it doesn’t alter the spray’s movement in the air itself.
